Thread: What do you make of this behaviour

Early dominance training and socialising is important (or has been for me with pups anyway).
Its probably not too late to do this with Bo:

Put him on his back and calm him. Hold him with your hands on his tummy. Don't let him move. If he moves, calmly rebuke him "no Bo" and tighten your grip a little. Relax your grip when he relaxes. Get him so he is completely submissive on his back - just laying completely still for as long as you want. You are in charge. I start this at about 8 weeks with pups.

I progress to taking food off them at the kennel. If they pull back or snap, I rebuke. You should be able to put your hand around their mouth and face when they are eating and be able to take food from them without the slightest display of aggression or ownership from them. Any aggression and they get a sharp "no", and sometimes a tap on the nose. When you give the bone (say) back they should take it gently and not snatch it. You should be able to put your hand in their mouth while they are eating.

None of this came from a book. Just my own home spun wisdom and what I learnt from shepherds and farm doggy people. Ive had dozens of working dogs in my lifetime.
